Abacus at Kusaba teaches abacus and mental math to kids from about 4.5 to 13, starting from its Amstelveen center, which opened in 2015. Kids move through graded levels of three to four months each in a weekly 90-minute lesson, and earn a certificate at the end of every level. Students can also take part in international abacus boot camps and championships.
